Flashcards

Where are the adrenal glands located?

The adrenal glands are located on top of the kidneys, with the right gland being triangular and higher than the left, which is semilunar and lower.

Right adrenal gland shape and position

The right adrenal gland is triangular in shape and located higher than the left adrenal gland.

Left adrenal gland shape and position

The left adrenal gland is semilunar in shape and lower, reaching the hilum.

Blood supply to adrenal glands

The adrenal glands receive blood from three arteries: the superior adrenal artery (from the phrenic artery), the middle adrenal artery (directly from the aorta), and the inferior adrenal artery (from the renal artery).

Blood drainage from adrenal glands

The right adrenal vein is short and drains directly into the inferior vena cava (IVC), with the hilum pointing upwards. The left adrenal vein is long and drains into the left renal vein, with the hilum pointing downwards.

Study Notes

Suprarenal Glands: Anatomy

Location: Suprarenal glands sit atop the kidneys.
Shape: The right suprarenal gland is triangular, while the left is semilunar.
Position: The right gland is higher, on the upper pole of the kidney. The left gland is lower and extends towards the renal hilum.
Relations (Posterior): Both glands are related to the upper pole of the respective kidney and the diaphragm.
Relations (Anterior):
Right gland: Inferior vena cava (IVC) and the right lobe of the liver.
Left gland: Stomach and the body of the pancreas.

Blood Supply

Anterior Supply (both):
Superior suprarenal artery (from phrenic artery).
Middle suprarenal artery (from aorta).
Inferior suprarenal artery (from renal artery).

Venous Drainage

Right Vein: Short, draining into the inferior vena cava (IVC). Hilum directed upwards.
Left Vein: Long, draining into the left renal vein. Hilum directed downwards.
